TO ALL WIIOM IT MAY CONCERN:

Bc it known that I, WILLIAM H. LAUBACII, of the city of Philadelphia., and State of Pennsylvania, have invented an Improved Apparatus for Carbonizing Illuminating-Gas; and I do hereby declare that the following is a full, clear, and cxactvdescription ot' the same, reference being had to the annexed drawing, and the letters of reference .marked thereon.. I I

The nature of -'my intention consists of an apparatus by which ordinary illuminating-gas is intimately and eilectualiymixd with the vapor of volatile oils or other substances rich in carbon, and which are evaporated at a low temperature, in connection with a glass gauge-tube, (which vindicates the surface-level of the fluid in vthechamber of said apparatus,) as hereinafter described'.

Tofenable others skilled in the art to make and use my invention, I will proceed to describe its construction and operation. v v i Itwill be composed of tin or other suitable metal, and `is intended to be attached to a gas-pipe, between the m'etertand burners. l

Figure 1 is a perspective view of the outside of the apparatus, with the glass gauge-tube and supply-tube in section. i

Figure 2 is a. horizontal section through the red line a b', fig. 1.

Figure 3 is a sectional elevation through the red line c' d', figfl.

Similar letters designate similar parts in all the figures.

To the side and top-plates of an ordinary oblong case,A, iig. 1, are fixed across inside, parallel. to each other, the division-plates a a a, ttc., iig. 2, each being attached alternately to the opposite sdeplatesand all being attached to the top-plate, fig. 3. They extend nearly to the bottom-plate, and are about two-thirdsot` the width of thev case, so that an opening of about* ono-third the width is left between thc 'edge of each plate and the opposite side-plate. i

To the bottom-plate are attached, parallel to each other, and across the said casing, the'division-plates b b b,-

&c., figs. 2 and 3, extending nearly toV the top-plate, but about being only half the width of the'casing, and placcdin the middle of the bottom-plate. An open space isA left at cach edge of the said plates, between it and the sides of the casing. These division-plates are placed in the centre of the spaces left between the plates a a a, &c.

The chamber B, figs. 2 and 3, in the interior of the casing, is thus subdivided into numerous cells or pas sages, communicating with cach other by the spaces left between the edges of the division-plates and the sides, top, and bottom of the casing. These are'again subdivided b'y loosely placing mnslin or other fibrous material, c c c, ttc., gs. 2 and between the division-plates, by which arrangement the gas llowng through the chamber B is made to traverse all the divisions thus formed. t

The open cnds of the glass gauge-tube C, iig. 1, which is hollow, lit into sockets in the caps ff, and are pressed tightly against the leather packing-rings z' t', by means of the strap d d, (which passes around them,) and set-screw e, inserted into a cap attached to the upper ends of the said strap. Thus the said gauge-tube is held firmly in place, and attached to the caps ff, which are fastened to the tubes g g, inserted into the top and side of the casing A, and thus a free communication is always secured between the hollow in the said gaugetube C and the chamber B, tige. 2 and 3, by means of the openings-'n n, through the leather packing and inner rings of thc'caps ff, and the tubes gig; consequently, the surface-level of the Huid in chamber B and that in the interior of the glass gaugetube C arc-the same.

The strap d d forms a guard to the glass tube 0,' and thc upper tube, g, is made long, so as to allow of sufiicient spring or vibration to admit of tightening the gauge-tube joints. There are also a supply-tube, F',.an inlet-tube, D, and an outlet-tube, E, inserted in and attached to the top-plate of the casing.

Agreeably to the above description, the apparatus being attached to the gas-pipe as before mentioned, and

the chamber B being partly iilled with the proper lluid through the supply-tube I, which is then closed, the

gas, under the ordinary pressure, is introduced into the chamber B, through the inlet-pipe D, and in its passage is made to traverse, in'an attenuated stream, ,through all the passages into'which the saidchamber is divided, and thus comes in Contact with the duid and vapor contained therein, and is eiectually carbonzed by the large proportion ofthe vapor which it absorbs. 4It then passes, through the outlet-pipe E, into the pipe for supply- Ving the burners, its illuminating-power being largely increased at a very trilling cost.

I do not claim the closed chamber B, with libro/us material, nor `the lzigzag passages, as these are described in the patents of J. F Boynton, September 25, 1866, and ,O'ctoher 8, 1867; but i What I do claim is- The hollow glass gauge-tube 0,. eaps j' f, straps did, set-serew'e, `and tubes g g, in yc mnhinaton, made inl the manner. and for the purpose described.
